We have come up with these top rated AGM battery charger buying guide and FAQs to help out people who are still confused with what to pick for their battery chargers.

The Best AGM Battery Charger Buying Guide & FAQ

Long before, there was only one type of charger to be used by all kinds of batteries. As the years went by, many different battery types have entered the market. With the growing numbers of cells available in the market today, there is also an increase in the clamor for a versatile battery charger.

What Is The Difference Between AGM Battery Charger And Regular Charger?

AGM batteries get its share in the market in the year 1980s. Since then, the name AGM became popular in the field of car batteries. AGM is a sealed lead acid battery which is used for vehicles, military aircraft and UPS which reduces the weight and improved reliability.

AGM stands for Absorbent Glass Material which means that it has an absorbent material between the battery plates. This porous material keeps and holds the fluid that is typically found in batteries.

Conventional chargers may not protect your cells against overcharging. Thus, when you use standard chargers, you have to monitor it closely.

AGM Chargers Features:

● Fast charging abilities.
● It has an automatic shut off.
● It has a built-in temperature sensor.
● It can detect the voltage of the battery it is charging.
● It has a jumpstart feature.

Standard Charger Features:

● It has a quick charge capabilities.
● It may or may not have an auto shut off.
● It may detect the voltage of the battery you are charging.
● It can also have jumpstart features.

Overall, some standard chargers can also have the features of an AGM charger. But in general, we have summed up the differences between the two:

● They differ in the speed in which the device supplies the charge to the cells.
● The specific features are found on the latest model of AGM chargers. Most conventional type chargers do not bear these advanced features.
● Only AGM chargers can be used for deep cycle batteries.
● AGM chargers are small and compact compared to standard batteries.
● AGM chargers have the anti-spark features which make it a lot safer than the most conventional type of chargers.

What Kind Of AGM Battery Charger Do I need?

There are things that you need to consider when buying an AGM charger. Although all AGM chargers are top quality, there is one particular charger that will suit your needs.

Step 1: You should determine your battery type. Batteries can be VRLA, AGM, wet and gel batteries. Be sure to know that you indeed have an AGM battery. All of these types of cells can work well with an AGM charger except for gel type batteries.

Step 2: Determine the size of your batteries. We are referring to the voltage size of the cells and not the physical dimension. The size of your battery depends on the number of Amperes it can store. If you have bigger Amps, then choose a charger with more Amps.

Step 3: You have to determine the charging performance. Depending on the vehicle you are using, you should be able to determine the right charger for you. If you want a fast charger, then choose something that enables quick charging time. If what you want is to keep your battery alive during long storage time, then select a charger with a maintenance mode or trickle mode.

Can I Use A Regular Charger For An AGM Battery?

An AGM battery is designed for slow and low charging. Therefore, using a regular charger for an AGM battery is not possible. An ordinary array may tend to overcharge the AGM cells and overcharging can kill batteries.

Remember that a regular charger cannot charge Absorbent Glass Material batteries.

Does AGM Battery Charger Charge Gel Batteries?

We have mentioned this earlier, and Gel batteries cannot be charged with an AGM charger. It has a different component which may create damage on the battery itself.

Though AGM and Gel batteries look similar, they are different from one another. Gel Cell is so sensitive that they should be charged correctly or they will suffer prematurely.

AGM Battery Charging Time

Battery charging time varies from one battery to the other. If you only aim for a maintenance charge, the charging time will run from 1 hour and should not exceed 4 hours charging time.

When the battery is expected to reach a full charge mode, it usually takes not more than 10 to 12 hours. We typically regard this as the absorption stage.

AGM Battery Charging Amps Rate

A charge rate of 14.5 V will normally charge a lead-acid battery. However, temperature control is crucial in determining the charging speed of a cell as it changes based on the temperature.

For example, if we are currently at 20 degrees, a 12V battery should already be float charged at 13.5V, however with the same cell, it should be charged at 13.3V when the temperature reaches 30 degrees.

AGM Battery Voltage Range

























This AGM battery voltage charts shows the battery ‘s state of charge and the range of voltage it reached when fully charged.

After going through the 6 Best AGM battery chargers, you are now fully equipped to buy which AGM charger will work best for you. We have reviewed each one carefully and the only thing that matters now is the price and the one that will suit you best.
